Wire-dot printer having printing wire driving device and manufacturing method thereof. |
摘要 |
A lever (130) for driving printing wires (198) has its outer end hooked to form a rotation support portion (196). A frame (100) for enclosing driving coils (130) and others has a yoke (150) having projections same in number as that of levers disposed on its end surface. The lever has the hooked supporting point locked by a recession formed between the yoke projections and an end surface (114) of the frame and fixed by a retainer spring (210). When an exciting current flows to the coils, the printing wires are struck on a platen round the supporting point. Since the lever is not provided with a rotating shaft member, the size in a cross direction is minimized. Accordingly, the number of levers enclosable in the frame is multiplied to enhance a packaging density. |
